Multi-speed Ports

If a port supports multiple speeds, the software configures the speed automatically based on the optic type it detects in the port; you do not need to configure the port speed. For multi-speed copper ports, Auto-Negotiation detects the speed.

Note

Note

Some VIMs must operate with all ports at the same speed, while others can operate with ports at different speeds. For more information, see VSP 8600 Release Notes. The sys vim-speed command is supported only on VIMs that must operate with all ports at the same speed. An error message displays if you run the command on an unsupported VIM.

In addition to the documented maximum port speed, and in cases where the hardware supports it:

SFP28, SFP+ and SFP ports have the same physical size.

QSFP28 and QSFP+ ports have the same physical size.

To know if a port supports multiple speeds or channelization, see the applicable hardware documentation.
